Objective To estimate the development of ossicular chain(OC)in patients with cholesteatomatous otitis media by multiplanar reformation(MPR)and Curved Planar Reformation(CPR)of HRCT.Methods To evaluate the sensitivity and specificity of CT axial,MPR,and CPR images in displaying ossicular chain destruction in 34 patients with 37 ears of cholesteatomatous otitis media confirmed by surgery and pathology,and to compare them with intraoperative results.Results The sensitivity and specificity of MPR for malleus bone destruction were 100％,while the sensitivity and specificity of MPR and CPR for incus bone destruction were 97.1％and 91.2％,respectively,and both were 100％.The sensitivity and specificity of MPR and CPR for stapes bone destruction were 88.9％and 84.2％.The sensitivity and specificity of MPR for malleus and incus joint bone destruction were 100％,and the sensitivity and specificity of CPR for incus and stapes joint bone destruction were 100％.Conclusion The MPR and CPR of Temporal Bone HRCT can provide reliable imaging reference data for the feasibility of surgery by estimating the development of OC in patients with cholesteatomatous otitis media.
